Indoor garden center with a plant pod detection system

ABSTRACT

An indoor gardening appliance includes a liner defining a grow chamber and a grow module mounted within the grow chamber for receiving a plurality of plant pods. The grow module defines a root chamber and a plurality of apertures for positioning a root end of the plant pod in the root chamber. A resonator may be positioned on each plant pod or at each of the plurality of apertures for generating a unique sound signature when a specific plant pod is inserted into a specific aperture. A detection device, such as a microphone, measures the sound waves generated by the resonator and a controller determines a location and/or a type of the plant pod based on the unique sound signature.

FIELD OF THE INVENTION

The present subject matter relates generally to systems for gardening plants indoors, and more particularly, to systems and methods for detecting the location and/or type of plant pods as they are installed into an indoor gardening appliance.

BACKGROUND OF THE INVENTION

Conventional indoor garden centers include a cabinet defining a grow chamber having a number of trays or racks positioned therein to support seedlings or plant material, e.g., for growing herbs, vegetables, or other plants in an indoor environment. In addition, such indoor garden centers may include an environmental control system that maintains the growing chamber at a desired temperature or humidity. Certain indoor garden centers may also include hydration systems for watering the plants and/or artificial lighting systems that provide the light necessary for such plants to grow.

However, conventional indoor gardens centers rely solely on the user or gardener to appropriately position plants or seedlings at the desired locations in the grow chamber. In addition, pruning, plant care, and other maintenance activities are typically implemented strictly based on the user's perception or observation and not necessarily based on a plant's needs. Moreover, watering schedules are typically automated at fixed intervals, which may not be preferable for certain plants.

Notably, these passive plant care systems require significant user interaction and manipulation, in large part because the indoor garden center has no knowledge of the type, position, grow times, or other details regarding the various plants positioned therein. Better knowledge of the type and position of plant pods would provide improved versatility and control over the chamber climate in a manner that facilitates improved plant growth and care.

Accordingly, an improved indoor garden center would be useful. More particularly, an indoor garden center with features that facilitate improved plant care, positioning, pruning, and feeding would be particularly beneficial.

As used herein, terms of approximation, such as “approximately,” “substantially,” or “about,” refer to being within a ten percent (10%) margin of error of the stated value. Moreover, as used herein, the terms “first,” “second,” and “third” may be used interchangeably to distinguish one component from another and are not intended to signify location or importance of the individual components. The terms “upstream” and “downstream” refer to the relative direction with respect to fluid flow in a fluid pathway. For example, “upstream” refers to the direction from which the fluid flows, and “downstream” refers to the direction to which the fluid flows.

FIG. 1 provides a front view of a gardening appliance 100 according to an exemplary embodiment of the present subject matter. According to exemplary embodiments, gardening appliance 100 may be used as an indoor garden center for growing plants. It should be appreciated that the embodiments described herein are intended only for explaining aspects of the present subject matter. Variations and modifications may be made to gardening appliance 100 while remaining within the scope of the present subject matter.

Gardening appliance 100 includes a housing or cabinet 102 that extends between a top 104 and a bottom 106 along a vertical direction V, between a first side 108 and a second side 110 along a lateral direction L, and between a front side 112 and a rear side 114 along a transverse direction T. Each of the vertical direction V, lateral direction L, and transverse direction T are mutually perpendicular to one another and form an orthogonal direction system.

Gardening appliance 100 may include an insulated liner 120 positioned within cabinet 102. Liner 120 may at least partially define a temperature controlled, referred to herein generally as a grow chamber 122, within which plants 124 may be grown. Although gardening appliance 100 is referred to herein as growing plants 124, it should be appreciated that other organisms or living things may be grown or stored in gardening appliance 100. For example, algae, fungi (e.g., including mushrooms), or other living organisms may be grown or stored in gardening appliance 100. The specific application described herein is not intended to limit the scope of the present subject matter.

Cabinet 102, or more specifically, liner 120 may define a substantially enclosed back region or portion 130. In addition, cabinet 102 and liner 120 may define a front opening, referred to herein as front display opening 132, through which a user of gardening appliance 100 may access grow chamber 122, e.g., for harvesting, planting, pruning, or otherwise interacting with plants 124. According to an exemplary embodiment, enclosed back portion 130 may be defined as a portion of liner 120 that defines grow chamber 122 proximate rear side 114 of cabinet 102. In addition, front display opening 132 may generally be positioned proximate or coincide with front side 112 of cabinet 102.

Gardening appliance 100 may further include one or more doors 134 that are rotatably mounted to cabinet 102 for providing selective access to grow chamber 122. For example, FIG. 1 illustrates doors 134 in the closed position such that they may help insulate grow chamber 122. By contrast, FIG. 2 illustrates doors 134 in the open positioned for accessing grow chamber 122 and plants 124 stored therein. Doors 134 may further include a transparent window 136 through which a user may observe plants 124 without opening doors 134.

Although doors 134 are illustrated as being rectangular and being mounted on front side 112 of cabinet 102 in FIGS. 1 and 2, it should be appreciated that according to alternative embodiments, doors 134 may have different shapes, mounting locations, etc. For example, doors 134 may be curved, may be formed entirely from glass, etc. In addition, doors 134 may have integral features for controlling light passing into and/or out of grow chamber 122, such as internal louvers, tinting, UV treatments, polarization, etc. One skilled in the art will appreciate that other chamber and door configurations are possible and within the scope of the present invention.

According to the illustrated embodiment, cabinet 102 further defines a drawer 138 positioned proximate bottom 106 of cabinet 102 and being slidably mounted to cabinet for providing convenient storage for plant nutrients, system accessories, water filters, etc. In addition, behind drawer 138 is a mechanical compartment 140 for receipt of an environmental control system including a sealed system for regulating the temperature within grow chamber 122, as described in more detail below.

FIG. 3 provides a schematic view of certain components of an environmental control system 148 that may be used to regulate a temperature within grow chamber 122. Specifically, environmental control system 148 may include a sealed system 150, a duct system 160, and a hydration system 270, or any other suitable components or subsystems for regulating an environment within grow chamber 122, e.g., for facilitating improved or regulated growth of plants 124 positioned therein. Specifically, FIG. 3 illustrates sealed system 150 within mechanical compartment 140. Although an exemplary sealed system is illustrated and described herein, it should be appreciated that variations and modifications may be made to sealed system 150 while remaining within the scope of the present subject matter. For example, sealed system 150 may include additional or alternative components, different ducting configurations, etc.

As shown, sealed system 150 includes a compressor 152, a first heat exchanger or evaporator 154 and a second heat exchanger or condenser 156. As is generally understood, compressor 152 is generally operable to circulate or urge a flow of refrigerant through sealed system 150, which may include various conduits which may be utilized to flow refrigerant between the various components of sealed system 150. Thus, evaporator 154 and condenser 156 may be between and in fluid communication with each other and compressor 152.

During operation of sealed system 150, refrigerant flows from evaporator 154 and to compressor 152, and compressor 152 is generally configured to direct compressed refrigerant from compressor 152 to condenser 156. For example, refrigerant may exit evaporator 154 as a fluid in the form of a superheated vapor. Upon exiting evaporator 154, the refrigerant may enter compressor 152, which is operable to compress the refrigerant. Accordingly, the pressure and temperature of the refrigerant may be increased in compressor 152 such that the refrigerant becomes a more superheated vapor.

Condenser 156 is disposed downstream of compressor 152 and is operable to reject heat from the refrigerant. For example, the superheated vapor from compressor 152 may enter condenser 156 and transfer energy to air surrounding condenser 156 (e.g., to create a flow of heated air). In this manner, the refrigerant condenses into a saturated liquid and/or liquid vapor mixture. A condenser fan (not shown) may be positioned adjacent condenser 156 and may facilitate or urge the flow of heated air across the coils of condenser 156 (e.g., from ambient atmosphere) in order to facilitate heat transfer.

According to the illustrated embodiment, an expansion device or a variable electronic expansion valve 158 may be further provided to regulate refrigerant expansion. During use, variable electronic expansion valve 158 may generally expand the refrigerant, lowering the pressure and temperature thereof. In this regard, refrigerant may exit condenser 156 in the form of high liquid quality/saturated liquid vapor mixture and travel through variable electronic expansion valve 158 before flowing through evaporator 154. Variable electronic expansion valve 158 is generally configured to be adjustable, e.g., such that the flow of refrigerant (e.g., volumetric flow rate in milliliters per second) through variable electronic expansion valve 158 may be selectively varied or adjusted.

Evaporator 154 is disposed downstream of variable electronic expansion valve 158 and is operable to heat refrigerant within evaporator 154, e.g., by absorbing thermal energy from air surrounding the evaporator (e.g., to create a flow of cooled air). For example, the liquid or liquid vapor mixture refrigerant from variable electronic expansion valve 158 may enter evaporator 154. Within evaporator 154, the refrigerant from variable electronic expansion valve 158 receives energy from the flow of cooled air and vaporizes into superheated vapor and/or high quality vapor mixture. An air handler or evaporator fan (not shown) is positioned adjacent evaporator 154 and may facilitate or urge the flow of cooled air across evaporator 154 in order to facilitate heat transfer. From evaporator 154, refrigerant may return to compressor 152 and the vapor-compression cycle may continue.

As explained above, environmental control system 148 includes a sealed system 150 for providing a flow of heated air or a flow cooled air throughout grow chamber 122 as needed. To direct this air, environmental control system 148 includes a duct system 160 for directing the flow of temperature regulated air, identified herein simply as flow of air 162 (see, e.g., FIG. 3). In this regard, for example, an evaporator fan can generate a flow of cooled air as the air passes over evaporator 154 and a condenser fan can generate a flow of heated air as the air passes over condenser 156.

These flows of air 162 are routed through a cooled air supply duct and/or a heated air supply duct (not shown), respectively. In this regard, it should be appreciated that environmental control system 148 may generally include a plurality of ducts, dampers, diverter assemblies, and/or air handlers to facilitate operation in a cooling mode, in a heating mode, in both a heating and cooling mode, or any other mode suitable for regulating the environment within grow chamber 122. It should be appreciated that duct system 160 may vary in complexity and may regulate the flows of air from sealed system 150 in any suitable arrangement through any suitable portion of grow chamber 122.

Gardening appliance 100 may include a control panel 170. Control panel 170 includes one or more input selectors 172, such as e.g., knobs, buttons, push buttons, touchscreen interfaces, etc. In addition, input selectors 172 may be used to specify or set various settings of gardening appliance 100, such as e.g., settings associated with operation of sealed system 150. Input selectors 172 may be in communication with a processing device or controller 174. Control signals generated in or by controller 174 operate gardening appliance 100 in response to input selectors 172. Additionally, control panel 170 may include a display 176, such as an indicator light or a screen. Display 176 is communicatively coupled with controller 174 and may display information in response to signals from controller 174. Further, as will be described herein, controller 174 may be communicatively coupled with other components of gardening appliance 100, such as e.g., one or more sensors, motors, or other components.

As used herein, “processing device” or “controller” may refer to one or more microprocessors or semiconductor devices and is not restricted necessarily to a single element. The processing device can be programmed to operate gardening appliance 100. The processing device may include, or be associated with, one or more memory elements (e.g., non-transitory storage media). In some such embodiments, the memory elements include electrically erasable, programmable read only memory (EEPROM). Generally, the memory elements can store information accessible processing device, including instructions that can be executed by processing device. Optionally, the instructions can be software or any set of instructions and/or data that when executed by the processing device, cause the processing device to perform operations.

Referring now generally to FIGS. 1 through 8, gardening appliance 100 generally includes a rotatable carousel, referred to herein as a grow module 200 that is mounted within liner 120, e.g., such that it is within grow chamber 122. As illustrated, grow module 200 includes a central hub 202 that extends along and is rotatable about a central axis 204. Specifically, according to the illustrated embodiment, central axis 204 is parallel to the vertical direction V. However, it should be appreciated that central axis 204 could alternatively extend in any suitable direction, e.g., such as the horizontal direction. In this regard, grow module 200 generally defines an axial direction, i.e., parallel to central axis 204, a radial direction R that extends perpendicular to central axis 204, and a circumferential direction C that extends around central axis 204 (e.g. in a plane perpendicular to central axis 204).

Grow module 200 may further include a plurality of partitions 206 that extend from central hub 202 substantially along the radial direction R. In this manner, grow module 200 defines a plurality of chambers, referred to herein generally by reference numeral 210, by dividing or partitioning grow chamber 122. Referring specifically to a first embodiment of grow module 200 illustrated in FIGS. 1 through 8, grow module 200 includes three partitions 206 to define a first chamber 212, a second chamber 214, and a third chamber 216, which are circumferentially spaced relative to each other. In general, as grow module 200 is rotated within grow chamber 122, the plurality of chambers 210 define substantially separate and distinct growing environments, e.g., for growing plants 124 having different growth needs.

More specifically, partitions 206 may extend from central hub 202 to a location immediately adjacent liner 120. Although partitions 206 are described as extending along the radial direction, it should be appreciated that they need not be entirely radially extending. For example, according to the illustrated embodiment, the distal ends of each partition is joined with an adjacent partition using an arcuate wall 218, which is generally used to support plants 124.

Notably, it is desirable according to exemplary embodiments to form a substantial seal between partitions 206 and liner 120. Therefore, according to an exemplary embodiment, grow module 200 may define a grow module diameter 220 (e.g., defined by its substantially circular footprint formed in a horizontal plane). Similarly, enclosed back portion 130 of liner 120 may be substantially cylindrical and may define a liner diameter 222. In order to prevent a significant amount of air from escaping between partitions 206 and liner 120, liner diameter 222 may be substantially equal to or slightly larger than grow module diameter 220.

According to still other embodiments, grow module 200 may include one or more sealing elements 224 positioned on a radially distal end of each of partitions 206. In this regard, sealing elements 224 may extend from partitions 206 toward liner 120 to contact and seal against liner 120. For example, according to the illustrated embodiment, sealing elements 224 are wiper blades formed from silicone or another suitably resilient material. Thus, as grow module 200 rotates, sealing elements 224 slide against liner 120 to substantially seal each of the plurality of chambers 210. It should be appreciated that as used herein, the term “substantial seal” and the like is not intended to refer to a perfectly airtight junction. Instead, this term is generally used to refer to an environment which may be regulated independently of adjacent environments to a reasonable degree. For example, if plants 124 and the first chamber 212 prefer a 10° F. increase in temperature relative to plants 124 and second chamber 214, the substantial seal between these two chambers may facilitate such temperature difference.

Referring now specifically to FIG. 3, gardening appliance 100 may further include a motor 230 or another suitable driving element or device for selectively rotating grow module 200 during operation of gardening appliance 100. In this regard, according to the illustrated embodiment, motor 230 is positioned below grow module 200, e.g., within mechanical compartment 140, and is operably coupled to grow module 200 along central axis 204 for rotating grow module 200.

As used herein, “motor” may refer to any suitable drive motor and/or transmission assembly for rotating grow module 200. For example, motor 230 may be a brushless DC electric motor, a stepper motor, or any other suitable type or configuration of motor. For example, motor 230 may be an AC motor, an induction motor, a permanent magnet synchronous motor, or any other suitable type of AC motor. In addition, motor 230 may include any suitable transmission assemblies, clutch mechanisms, or other components.

According to an exemplary embodiment, motor 230 may be operably coupled to controller 174, which is programmed to rotate grow module 200 according to predetermined operating cycles, based on user inputs (e.g. via touch buttons 172), etc. In addition, controller 174 may be communicatively coupled to one or more sensors, such as temperature or humidity sensors, positioned within the various chambers 210 for measuring temperatures and/or humidity, respectively. Controller 174 may then operate motor 230 in order to maintain desired environmental conditions for each of the respective chambers 210. For example, as will be described in more detail below, gardening appliance 100 includes features for providing certain locations of gardening appliance 100 with light, temperature control, proper moisture, nutrients, and other requirements for suitable plant growth. Motor 230 may be used to position specific chambers 210 where needed to receive such growth requirements.

According to an exemplary embodiment, such as where three partitions 206 form three chambers 212-216, controller 174 may operate motor 230 to index grow module 200 sequentially through a number of preselected positions. More specifically, motor 230 may rotate grow module 200 in a counterclockwise direction (e.g. when viewed from a top of grow module 200) in 120° increments to move chambers 210 between sealed positions and display positions. As used herein, a chamber 210 is considered to be in a “sealed position” when that chamber 210 is substantially sealed between grow module 200 (i.e., central hub 202 and adjacent partitions 206) and liner 120. By contrast, a chamber 210 is considered to be in a “display position” when that chamber 210 is at least partially exposed to front display opening 132, such that a user may access plants 124 positioned within that chamber 210.

For example, as illustrated in FIGS. 4 and 5, first chamber 212 and second chamber 214 are both in a sealed position, whereas third chamber 216 is in a display position. As motor 230 rotates grow module 200 by 120 degrees in the counterclockwise direction, second chamber 214 will enter the display position, while first chamber 212 and third chamber 216 will be in the sealed positions. Motor 230 may continue to rotate grow module 200 in such increments to cycle grow chambers 210 between these sealed and display positions.

Referring now generally to FIGS. 4 through 8, grow module 200 will be described in more detail according to an exemplary embodiment of the present subject matter. As shown, grow module 200 defines a plurality of apertures 240 which are generally configured for receiving plant pods 242 into an internal root chamber 244. Plant pods 242 generally contain seedlings or other material for growing plants positioned within a mesh or other support structure through which roots of plants 124 may grow within grow module 200. A user may insert a portion of plant pod 242 (e.g., a seed end or root end 246) having the desired seeds through one of the plurality of apertures 240 into root chamber 244. A plant end 248 of the plant pod 242 may remain within grow chamber 210 such that plants 124 may grow from grow module 200 such that they are accessible by a user. In this regard, grow module 200 defines root chamber 244, e.g., within at least one of central hub 202 and the plurality of partitions 206. As will be explained below, water and other nutrients may be supplied to the root end 246 of plant pods 242 within root chamber 244. Notably, apertures 240 may be covered by a flat flapper seal (not shown) to prevent water from escaping root chamber 244 when no plant pod 242 is installed.

As best shown in FIGS. 5 and 7, grow module 200 may further include an internal divider 250 that is positioned within root chamber 244 to divide root chamber 244 into a plurality of root chambers, each of the plurality of root chambers being in fluid communication with one of the plurality of grow chambers 210 through the plurality of apertures 240. More specifically, according to the illustrated embodiment, internal divider 250 may divide root chamber 244 into a first root chamber 252, a second root chamber 254, and a third root chamber 256. According to an exemplary embodiment, first root chamber 252 may provide water and nutrients to plants 124 positioned in the first grow chamber 212, second root chamber 254 may provide water and nutrients to plants 124 positioned in the second grow chamber 214, and third root chamber 256 may provide water and nutrients to plants 124 positioned in the third grow chamber 216. In this manner, environmental control system 148 may control the temperature and/or humidity of each of the plurality of chambers 212-216 and the plurality of root chambers 252-256 independently of each other.

Environmental control system 148 may further include a hydration system 270 which is generally configured for providing water to plants 124 to support their growth. Specifically, according to the illustrated embodiment, hydration system 270 generally includes a water supply 272 and misting device 274 (e.g., such as a fine mist spray nozzle or nozzles). For example, water supply 272 may be a reservoir containing water (e.g., distilled water) or may be a direct connection municipal water supply. Misting device 274 may be positioned at a bottom of root chamber 244 and may be configured for charging root chamber 244 with mist for hydrating the roots of plants 124. Alternatively, misting devices 274 may pass through central hub 204 along the vertical direction V and periodically include a nozzle for spraying a mist or water into root chamber 244. Because various plants 124 may require different amounts of water for desired growth, hydration system 270 may alternatively include a plurality of misting devices 274, e.g., all coupled to water supply 272, but being selectively operated to charge each of first root chamber 252, second root chamber 254, and third root chamber 256 independently of each other.

Notably, environmental control system 148 described above is generally configured for regulating the temperature and humidity (e.g., or some other suitable water level quantity or measurement) within one or all of the plurality of chambers 210 and/or root chambers 252-256 independently of each other. In this manner, a versatile and desirable growing environment may be obtained for each and every chamber 210.

Referring now for example to FIGS. 4 and 5, gardening appliance 100 may further include a light assembly 280 which is generally configured for providing light into selected grow chambers 210 to facilitate photosynthesis and growth of plants 124. As shown, light assembly 280 may include a plurality of light sources 282 stacked in an array, e.g., extending along the vertical direction V. For example, light sources 282 may be mounted directly to liner 120 within grow chamber 122, or may alternatively be positioned behind liner 120 such that light is projected through a transparent window or light pipe into grow chamber 122. The position, configuration, and type of light sources 282 described herein are not intended to limit the scope of the present subject matter in any manner.

Light sources 282 may be provided as any suitable number, type, position, and configuration of electrical light source(s), using any suitable light technology and illuminating in any suitable color. For example, according to the illustrated embodiment, light source 282 includes one or more light emitting diodes (LEDs), which may each illuminate in a single color (e.g., white LEDs), or which may each illuminate in multiple colors (e.g., multi-color or RGB LEDs) depending on the control signal from controller 174. However, it should be appreciated that according to alternative embodiments, light sources 282 may include any other suitable traditional light bulbs or sources, such as halogen bulbs, fluorescent bulbs, incandescent bulbs, glow bars, a fiber light source, etc.

As explained above, light generated from light assembly 280 may result in light pollution within a room where gardening appliance 100 is located. Therefore, aspects of the present subject matter are directed to features for reducing light pollution, or to the blocking of light from light sources 282 through front display opening 132. Specifically, as illustrated, light assembly 280 is positioned only within the enclosed back portion 130 of liner 120 such that only grow chambers 210 which are in a sealed position are exposed to light from light sources 282. Specifically, grow module 200 acts as a physical partition between light assemblies 280 and front display opening 132. In this manner, as illustrated in FIG. 5, no light may pass from first chamber 212 or second chamber 214 through grow module 200 and out front display opening 132. As grow module 200 rotates, two of the three grow chambers 210 will receive light from light assembly 280 at a time. According still other embodiments, a single light assembly may be used to reduce costs, whereby only a single grow chamber 210 will be lit at a single time.

Gardening appliance 100 and grow module 200 have been described above to explain an exemplary embodiment of the present subject matter. However, it should be appreciated that variations and modifications may be made while remaining within the scope of the present subject matter. For example, according to alternative embodiments, gardening appliance 100 may be a simplified to a two-chamber embodiment with a square liner 120 and a grow module 200 having two partitions 206 extending from opposite sides of central hub 202 to define a first grow chamber and a second grow chamber. According to such an embodiment, by rotating grow module 200 by 180 degrees about central axis 206, the first chamber may alternate between the sealed position (e.g., facing rear side 114 of cabinet 102) and the display position (e.g., facing front side 112 of cabinet 102). By contrast, the same rotation will move the second chamber from the display position to the sealed position.

According to still other embodiments, gardening appliance 100 may include a three chamber grow module 200 but may have a modified cabinet 102 such that front display opening 132 is wider and two of the three grow chambers 210 are displayed at a single time. Thus, first chamber 212 may be in the sealed position, while second chamber 214 and third chamber 216 may be in the display positions. As grow module 200 is rotated counterclockwise, first chamber 212 is moved into the display position and third chamber 216 is moved into the sealed position.

Referring now specifically to FIGS. 9 and 10, gardening appliance 100 may further include a pod detection system 300 which is generally configured for detecting and identifying a type of plant pod 242 positioned within grow module 200, a particular location within grow module 200 where a particular plant pod 242 is positioned, and/or other data indicative of a particular plant pod 242 and its plant care or maintenance needs. Notably, pod detection system 300 may be operated in part by a controller (e.g., such as controller 174) which may use the improved knowledge regarding pod location or type to facilitate improved plant care and/or maintenance. Although an exemplary pod detection system 300 is described herein, it should be appreciated that the embodiment described is exemplary and intended to facilitate explanation of aspects of the present subject matter. However, the present subject matter is not intended to be limited to the embodiment described.

As used herein, the term “pod location” or the like is generally intended to refer to the position of a plant pod 242 in grow module 200. In this regard, for example, the pod location may refer to a particular side of grow module 202, e.g., plant pods 242 positioned in a particular grow chamber 252-256. In addition, or alternatively, the pod location may refer to a particular aperture 240 within an arcuate wall 218 of grow module 200. In this regard, for example, the exemplary illustrated embodiment of FIG. 9 shows nine apertures 240 on one of the arcuate walls 218 of grow module 200. According to such an embodiment, the pod location may refer to a particular aperture 240 by row and column designation (e.g., location A3 may refer to row A and column 3).

In addition, as used herein, the term “pod type” and the like may generally be intended to refer to the type of plant or seeds positioned within plant pod 242. In this regard, for example, a plant pod 242 may be identifiable as containing basil, rosemary, lettuce, or another seed or plant material. In addition, or alternatively, pod type may include data indicative of plant care or maintenance needs of the plant contained in a plant pod 242. In this regard, for example, the pod type may include information related to a desire watering schedule, nutrient concentrations, lighting schedules, pruning instructions, or other information related to the maintenance and care of the plant type associated with a particular plant pod 242.

In general, pod detection system 300 operates to obtain knowledge or data related to plant pods 242 installed within gardening appliance 100 by monitoring sound waves generated by plant pods 242 when installed into grow module 200. In this regard, as illustrated, pod detection system 300 may include one or more resonating devices, referred to herein as resonators 302. In general, resonators 302 may be any suitable structure or member that is configured for generating sound waves when triggered, e.g., such as when plant pod 242 is inserted through aperture 240 and contact or engages the resonator 302.

Resonators 302 may generally be any structure or device the generates sounds when it engages or interacts with a plant pod 242. In this regard, for example, resonators 302 may be one or more cantilevered metal springs, vibrating rods, or oscillating members. In addition, resonators 302 may be constructed of any suitable material, such as plastic, metal, or any other suitable rigid or resilient material.

Resonators 302 may be mounted directly to grow module 200, e.g., such as directly to an interior surface 304 of arcuate wall 218. In addition, according to exemplary embodiments, resonators 302 may be mounted using a hinge and spring arrangement, using a resilient connector, or in any other suitable manner. As illustrated, resonators 302 extend into aperture 240 such that plant pod 242 engages resonators 302 when inserted through aperture 240.

Pod detection system 300 may further include a detection device 310 that is used for monitoring the sound waves 312 generated by resonators 302. For example, detection device 310 may be one or more microphones 314 or any other suitable acoustic transducers that are positioned within gardening appliance 100 or otherwise within the acoustic range of resonators 302. For example, microphone 314 may be communicatively coupled to controller 174 for measuring sound waves generated by the resonators 302. Notably, the sound waves generate a unique sound signature that controller 174 may analyze to determine the pod type and/or location based at least in part on the measured sound waves 312.

According to exemplary embodiments, a single resonator 302 or a single sequence of resonators 302 may be positioned at each of the pod locations, e.g., adjacent each of the plurality of apertures 240. In this manner, when a plant pod 242 is inserted through the aperture 240 at that particular location, the sound waves 312 generated by the resonator 302 may create a unique sound signature, identifiable for example by natural resonant frequencies of the particular resonators 302, an excitation rate of the resonator 302 (i.e., the speed at which the resonator 302 is triggered), the time decay of the generated sound waves 312, or any other acoustic signature or characteristic. For example, referring again to FIG. 9, each of the pod locations from top to bottom, left to right, can have a resonator 302 having a different frequency. For example, the frequencies use may vary from 10 to 27 kHz in 2 or 3 kHz increments. It should be appreciated that other suitable frequency ranges and increments may be used while remaining within the scope of the present subject matter.

According to the illustrated embodiment, gardening appliance 100 includes a single microphone 314. However, it should be appreciated that according to alternative embodiments, multiple detection devices 310 may be used to facilitate pod type/location determination. For example, according to alternative exemplary embodiments, detection device 310 may include a plurality of microphones 314 that are spaced apart from each other, each detecting the sound waves 312 generated by resonators 302 when triggered. According to an exemplary embodiment, the plurality of microphones 314 may implement a triangulation technique to determine the location of plant pod 242 that is inserted through aperture 240.

Referring again to FIGS. 9 and 10, pod detection system 300 may further include excitation elements 320 that are configured for triggering or exciting resonators 302 when a plant pod 242 is inserted through an aperture 240. In this regard, according to the exemplary embodiment, excitation elements 320 may include one or more bumpers 322, recesses 324, or any other suitable protrusion, slot, aberration, or other feature that may be used to generate sound waves from resonators 302.

It should be appreciated that the size, geometry, or position of excitation elements 320 may vary to generate different excitation rates or frequencies from resonators 302. For example, each plant pod 242 may define a sequence of unique excitation elements 320 that generate a unique sequence of excitations when that plant pod 242 is inserted into one of apertures 240. The generated sound waves 312 may serve as an identifier and may depend on the sequence of excitation elements 320, the sequence of resonators 302, or some combination of both.

In order to ensure proper alignment between the resonators 302 and excitation elements 320, keyed features may be defined on plant pod 242 and grow module 200. For example, according to the illustrated embodiment, plant pod 242 may define a keyed feature 330 and grow module 200 may define a complementary recess 332 adjacent each aperture 240. In this manner, plant pod 242 may only be installed when positioned at a desired angle, e.g., such that the keyed feature 330 aligns with the complementary recess 332. Various keyed features having different sizes, shapes, and positioned are contemplated as within the scope of the present subject matter. In addition, according another exemplary embodiment, the plant pods 242 and grow module 200 may defined complementary threads, such that plant pods 242 are screwed into apertures 240. The excitation elements 320 and resonators 302 may then be defined on the complementary threads to ensure they engage each other when plant pod 242 is installed.

According to the illustrated embodiment, resonators 302 are mounted to grow module 200, e.g., on arcuate wall 218. In addition, excitation elements 320 are positioned on plant pods 242. However, it should be appreciated that according to alternative embodiments, any suitable combination of resonators 302 and excitation elements 320 may be positioned on either of plant pods 242 and grow module 200. For example, according to alternative embodiments, resonators 302 may be mounted directly onto plant pods 242. In addition, or alternatively, excitation elements 320 may be defined on grow module 200, e.g., within apertures 240. Other configurations are possible and within the scope of the present subject matter.

According to exemplary embodiments of the present subject matter, controller 174 may be configured for adjusting operating parameters of gardening appliance 100 based on the determined pod type and/or location. In this regard, the controller 174 can identify a plant pod 242 installed in grow module, and may determine that the plant pod 242 contains plant material that requires a particular watering or lighting schedule. The controller 174 may then adjust the operating parameters of gardening appliance 100 to provide light and water to the particular pod location in order to facilitate improved growth of that plant.

For example, according to an exemplary embodiment, the at least one operating parameter adjusted by a controller 174 based on the pod type and location may be the chamber temperature, a chamber humidity, a light setting, a nutrient schedule, and/or a user instruction related plant care. According to exemplary embodiments, the at least one operating parameter may be adjusting the light assembly 280 to provide a unique light intensity, light direction, time schedule, or wavelength of light energy. In addition, or alternatively, the at least one operating parameter adjusted by controller 174 based on the pod type and/or location may be the operation of hydration system 270, e.g., by adjusting the direction of hydrating fluid, the nutrient concentration, the spray schedule, or flow rate of a flow of hydrating fluid. According still other embodiments, controller 174 can adjust operation of sealed system 150, e.g., to control a temperature, humidity, or flow rate of the flow of air.
